Oral mucositis is a known complication of methotrexate (MTX) therapy, but a single efficacious intervention or agent for prophylaxis or management of this side effect has not yet been identified. We report a case of MTX-induced oral mucositis in a patient with rheumatoid arthritis, who was successfully treated with Wild chamomile mouthwashes. 相似文献

The phenotypic consequences in the house mouse (Mus musculus domesticus) of the transition from an ordinary field-dwelling rodent to a species that is dependent on human populations was studied by investigating the morphometric variation of non-commensal populations of M. m. domesticus from Syria, Jordan, SW Iran, and Libya and comparing them with that of conspecific commensal populations from Eastern Turkey, Greece, and Bulgaria. Commensal populations of M. musculus musculus from the Czech Republic were used as an outgroup. About 849 adult specimens of M. musculus were analysed by multivariate procedures based on standard molar, skull and body measurements. As expected, there was considerable variation among the studied populations and a good correspondence between morphometric and geographic distances. The resulting morphometric tree was consistent with the hypothesis that the original radiation of M. m. domesticus took place somewhere in the Near East. Commensal populations of M. m. domesticus form a single derived branch. Specimens originating from four different sites in eastern Syria showed the greatest similarity to one another and possessed relatively bigger molars than the other studied populations. Commensal populations were characterised by longer tails when compared to non-commensal populations, which suggests an adaptation for living in a more three-dimensionally heterogeneous environment for commensal populations. 相似文献

Nationalization and Globalization Trends in the Wild Mushroom Commerce of Italy with Emphasis on Porcini (
Boletus edulis
and Allied Species). This paper presents an historical overview of wild mushroom commerce in Italy, with a focus on recent trends in the production
of porcini (Boletus edulis and closely allied species). Over the past century, two major trends—nationalization and globalization—have been apparent
in the wild mushroom commerce of Italy. First, a simplified national mushroom menu has emerged through processes of governmental
regulation and culinary fashion, but it has come at the expense of differing, localized mushroom traditions which may suffer
under the European Union’s free trade principles. Second, Italy has emerged as a focal point of a global market for a small
number of mushroom species—particular porcini. While the name porcini has become synonymous with Italian cuisine, and in spite
of a vibrant tradition of recreational mushroom collecting in Italy, most of the porcini commercially available in Italy or
exported by Italy are no longer of Italian origin. Porcini and other mushrooms now flow into Italy from all over the world—especially
from China and eastern Europe—and are then often exported as “Italian porcini.” This globalization of the wild mushroom trade,
while offering significant income to rural producers and processors around the globe, has other effects as well, for example,
a kind of national branding as “Italian” of globally-produced products, of which porcini is one, that is in direct opposition
to some of the European Union’s rules for regional denominations.
Processi di Nazionalizzazione e Globalizzazione nel Commercio Italiano dei Funghi spontanei, con Particolare Riguardo ai Porcini ( Boletus edulis e Specie Affini). Questo articolo presenta una panoramica storica sul commercio dei funghi spontanei in Italia, con particolare riguardo alle recenti tendenze nella produzione dei porcini (Boletus edulis e specie affini). Nello scorso secolo si sono osservate due tendenze principali—di nazionalizzazione e di globalizzazione—nel commercio dei funghi spontanei in Italia. In primo luogo si è affermata nel territorio nazionale una tradizione limitata al consumo di un numero contenuto di specie, sia per effetto di alcune normative che di mode culinarie, ma ciò è avvenuto a discapito di tradizioni locali più ricche, che potrebbero ulteriormente risentire dei principi per il libero scambio all’interno dell’Unione Europea. In secondo luogo, l’Italia si è posta in evidenza come un punto nodale per il mercato globale di alcune specie fungine, in particolare dei porcini. Nonostante quest’ultimo termine sia tradizionalmente associato alla cucina italiana, e nonostante esista in Italia una vivace e radicata tradizione nella raccolta amatoriale dei funghi, la maggior parte dei porcini ivi commercializzati (allo stato fresco, essiccati o variamente conservati) o esportati verso altri paesi non sono più di origine locale. I porcini e altre specie fungine giungono attualmente in Italia da ogni parte del mondo—in modo particolare dalla Cina e dall’Europa orientale—e sono successivamente spesso esportati come “prodotti Italiani.” Questo processo di globalizzazione del mercato dei funghi spontanei, pur offrendo un significativo introito ai raccoglitori e commercianti rurali su tutto il globo, è responsabile di altri effetti, come per l’appunto una sorta di marchio nazionale “Italiano” su alcuni prodotti di provenienza globale, come per l’appunto i porcini, cosa che contrasta con alcune delle regole dell’Unione Europea in materia di denominazioni regionali.相似文献

Summary The competitive ability of the pollen of wild tomato species (Solanum pennellii, Lycopersicum hirsutum and L. minutum) and a cultivar of tomato to affect fertilization at low temperature was investigated. Pollen grains of wild species were mixed with those of the cultivar and pollinated onto the stigma of the cultivar. The number of seedlings resembling the wild species, excluding L. minutum, were significantly higher when the plants were maintained at a low temperature (8°–12° C) than when they were maintained at a normal temperature (22°–28° C). This indicates that the pollen of S. pennellii and L. hirsutum wild species can compete better with pollen of the cultivar at a low temperature, while there was no change in the competitive ability of L. minutum pollen under these conditions. 相似文献

The AFLP method was used to study the inter-population variability of eight populations of Elymus caninus (L.) L. as well as three populations of Hordelymus europaeus (L.) Jess. ex Harz. In these studies a clear distinction was found between two phenotypes of E. caninus collected in the same locality. It also appeared that two populations of E. caninus representing the “pauciflorum” morphotype were clustered together, similarly as two populations of E. caninus exhibiting morphotype “caninus”. Additionally, the populations of the “pauciflorum” type were clustered together with all
samples of H. europaeus. Furthermore, the same approach was applied to analyze the intra-population variability of E. caninus. The populations ranged from nearly uniform to as diverse as the samples collected from different localities. In some populations
of this species the presence of off-type plants was revealed. Our data indicate the predominantly self-pollinating character
of E. caninus and the possible genetic relationship between of E. caninus and H. europaeus.
It is the second paper from the series: Biodiversity of wild Triticeae (Poaceae) in Poland, the first is: Mizianty M. 2005.

黑龙江省通河乌龙狩猎场野猪冬季食性的初步研究 总被引:12,自引:3,他引:9
野生动物食性的研究,在野生动物保护和管理方面具有重要的基础理论意义。野猪(Sus scrofa)是一种经济价值较高的有蹄类动物。国内对野猪食性的报道,仅见综述性献(巫露平,1980;李振营和罗泽殉,1983;杨伯然,1984),野猪食性方面的研究尚未多见;国外对野猪食性的研究主要集中在食物组成的定量分析和食物营养质量的评价(Eriksson and Petrov,1995;Foumier-chambrillon et al.,1995;朝日念,1985)。因此,作从2000~2001年,分别在黑龙江省通河乌龙狩猎场收集粪样,利用粪便显微组织学分析方法并结合野外掘食痕迹对野猪冬季食性进行了初步研究。 相似文献

Two DNA fingerprinting techniques, random amplified polymorphic DNA (RAPD) and inter-retrotransposon amplified polymorphism
(IRAP), were used to characterize somaclonal variants of banana. IRAP primers were designed on the basis of repetitive and
genome-wide dispersed long terminal repeat (LTR) retrotransposon families for assessing the somaclonal variation in 2Musa clones resistant and susceptible toFusarium oxysporum f. sp.cubense race 4. RAPD markers successfully detected genetic variation within and between individuals of the clones. IRAP makers amplified
either by a single primer or a combination of primers based on LTR orientation successfully amplified different retrotransposons
dispersed in theMusa genome and detected new events of insertions. RAPD markers proved more polymorphic than IRAP markers. Somaclonal variation
seems to be the result of numerous indels occurring genome-wide accompanied by the activation of retroelements, as a result
of stress caused by micropropagation. It is concluded that characterization of the somaclonal variants requires more than
one DNA marker system to detect variation in diverse components of the genome. 相似文献

In this article we examine the natural habitats and distribution of the six wild cereals: Triticum urartu (wild urartu wheat), T. boeoticum aegilopoides (single-grained wild einkorn), T. boeoticum thaoudar (two-grained wild einkorn), T. dicoccoides (wild emmer wheat), Secale spp. (wild ryes) and Hordeum spontaneum (wild barley). A comparison of late Pleistocene/early Holocene archaeobotanical assemblages in the Near East with present-day
distributions of wild cereals shows a good correlation. The regional variation in the archaeobotanical cereal assemblages
and the ensuing domestication provide evidence that different cereal species were domesticated independently in different
areas. Some sites were not situated near wild cereal habitats and a few were located outside the limits of distribution, even
accounting for moister climatic conditions. I argue here that current models which try to explain the shift to farming have
tended to over-emphasize the effect of the Younger Dryas climatic change. First, it would have had only a minor effect on
cereal availability. Secondly, agriculture appears to have been established after the Younger Dryas. Thirdly, there is no
evidence for a single centre of origin; agriculture arose in widely separated geographic and climatic regions. And fourthly,
agriculture depends on stable climatic conditions which were not established until after the Younger Dryas. 相似文献
